Ludwig von Mises: Banned by Nazis, his theories led to German recovery

In the late 1930s, after suffering from the worldwide depression, Austria was threatened by a Nazi takeover. Hayek had already left for London in 1931 at Mises's urging, and in 1934, Mises himself moved to Geneva to teach and write at the International Institute for Graduate Studies, later emigrating to the United States. Knowing Mises as the sworn enemy of national socialism, the Nazis confiscated Mises's papers from his apartment and hid them for the duration of the war. Ironically, it was Mises's ideas, filtered through the work of Roepke and the statesmanship of Ludwig Erhard, that led to Germany's postwar economic reforms and rebuilt the country. Then, in 1992, Austrian archivists discovered Mises's stolen Vienna papers in a reopened archive in Moscow.
